You are gradually making progress in your programming journey and your love for programming continues to grow. You are developing an application for invoicing. Create a class called Purchase. Each Purchase must have an invoice number, amount of sale and an amount for sales tax. You have been reminded that you need to include set methods for the invoice number and sale amount. For the set method of the sale amount, calculate the sales tax as 5 percent of the sale amount. You have been again reminded that you need to include a display method that displays all the purchase's details.

Dice Rolling Class In this problem, you will need to create a program that simulates rolling dice. To start this project, you will first need to define the properties and behaviors of a single die that can be reused multiple times in your future code. This will be done by creating a Dice class. Create a Dice class that contains the following members: Two private integer variables to store the minimum and maximum roll possible. Two constructors that initialize the data members that store the min/max possible values of rolls. a constructor with default min/max values. a constructor that takes 2 input arguments corresponding to the min and max roll values Create a roll() function that returns a random number that is uniformly distributed between the minimum and maximum possible roll values. Create a small test program that asks the user to give a minValue and maxValue for a die, construct a single object of the Dice class with the constructor that initializes the min and max…
use this code template to help you continue: private boolean included Indicates whether the item should be taken or not public Item(String name, double weight, int value) Initializes the Item’s fields to the values that are passed in; the included Field is initialized to false public Item(Item other) Initializes this item’s fields to the be the same as the other item’s public void setIncluded(boolean included) Setter for the item’s included field (you don’t need setters for the other fields) Given code: public class Item { private final String name; private final double weight; private final int value; public Item(String name, double weight, int value) { this.name = name; this.weight = weight; this.value = value; } static int max(int a, int b) { if(a > b) return a; return b; } // function to print the items which are taken static void printSelection(int W, Item[] items, int…

JAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…
SwapPoints Objective: To write two missing functions that manipulate objects, to complete a given program. I recommend you start early on this and all programming assignments. They are an important part of your grade, and they use material from the notes and exercises we did in the previous module. (They don't relate to this module's notes or exercise.) So your job is to write the two functions below, which are missing from the program: inputNewPlayerLocation: to input (x,y) coordinates from user (using Scanner), then return a Point object with those coordinates. swapPoints: to swap the coordinates of two Point objects. (Hint: To keep the main function's reference variables relevant, you can't swap Point objects entirely. You need to change the x and y coordinates inside the Point objects.)
The weather generator methods you will be writing for this assignment will: predict future precipitation pattern for one month: oneMonthGenerator find the number of wet or dry days in a given month’s forecast: numberOfWetDryDays find the longest wet or dry spell in a given month’s forecast: lengthOfLongestWetDrySpell
Assignment using Methods For this exercise, you need to complete all the questions in a single project. You will invoke the methods from your main. Questions 1-6 is due at the end of your next class. Write a method with the following specifications:name: DisplayMenuarguments: nonereturn value: nonetasks: display the following menu choice on the screenCalculation Menu3) Calculate Sum 4) Calculate Sum of Squares5) Calculate Sum of Cubes0) To ExitEnter the number that corresponds to your choice: You may beautify the output to your own likings. You don’t have to implement the functionalities of the various menu choices at this stageCall this method from your main. Modify your main so that the above method is call repeatedly. The program will terminate when the user enters 0. Any other choice should produce an error message. Because you will not be doing any arithmetic you may accept the user response either as an int, or a char or a string. Write a method with the following…
Please refer to General Assignment requirements document for the additional requirementsPlease note that numbers in the square brackets before each requirement represent the points that are awarded if the requirement is fully implemented.In this assignment you will create an address book. The user of the application will be able to add a contact with the following information about the contact:1. First name2. Last name3. Address4. Phone numberTo implement this, you need to do the following:The Contact classYou will implement the Contact class in Visual Studio. A short description of the class members is given below. This class must have only the following members:Properties:You must use auto-implemented properties.[1] FirstName – string that represents the first name of the contact[1] LastName - string that represents the last name of the contact[1] Address - string that represents the address of the contact[1] Phone – unsigned long integer that represent a phone number of the…
Overview: A new bank wants to make a simple application to keep track of all accounts and transactions. In this TMA, it is required to help the bank manager implement the required application. Requirements: After a quick meeting with the bank manager, you got the following information: It is required to store all bank accounts in one collection and all the transactions happened in another collection. Each account has a unique account number, a holder and balance. There is a specific prefix (common for all accounts) that should be added to the holder's civil id to create the unique account number. In addition, it is not allowed for a holder to have more than one account. Furthermore, only three transactions are allowed on any account: deposit, withdrawal and transfer money to another account. Each holder has a unique civil ID (national id), a name and other attributes (add at least 2 attributes from your choice). For each transaction, it is required to store the account(s) affected,…
